OSCAR YDAMAN AND LOUISW. DAMAN, OF MINNEAPOLIS, MINNESOTA, AS- SIGNORS OF ONE-THIRD TO EDWARD D. PERKINS, OF SAME PLACE.

STAND-PIPE FOR GAsoLlN-E-BURNERS.

SPECIFICATION forming part of Letters Iatent No. 546,642, dated September 17, 1895.

Application iiledllpril 13, 1895. Serial No. 545,577. (No model.)

Generally stated,'the invention consists in providing within the stand-pipe a lateral par` tition having an opening and valve-seat, a

` valve having a stem and means for guiding A as a stove.

it, and a loat below the stem for opening and closing the port, as service requires. Y

Our improvements are illustrated in the accompanying drawings, in which- Figure l shows in perspective a gasolinestove supplied with our improvements; Fig.' 2, a central vertical section of the stand-pipe containing the feed-controlling devices of our improvement and showing the port open; Fig.' 3, a similar sectional view showing the port closed, and Fig. 4. a detail of a bridge used for guiding the valve-stem.

In such drawings, 1 designates a gasolinestove; 2, a supply-tank for gasoline; 3, the su p` ply-pipe extending from the tank to a burner, and 4. a burner. These parts may be oi' any usual or desired form or arrangement, and, obviously, our improvements may beused in connection with a lighting apparatus as well The vertical portion of the pipe next beneath the burner, commonly called the stand-pipe, is indicated by 5, and in this portion are provided our improvements. The inlet from the feed-pipe proper to this upright portion may be at the bottom'or at the side, as shown in the drawings.

In the top of the pipe 5 is screweda hollow plug 6, having near its middle a horizontal partition 7, in which is an opening 8 for a valve-stem, and the under side of the opening is made tapering, as shown at 9, to serve as a seat for a conical valve 10, the valve being on a stem 11, which tits loosely in the opening 8,

so as to permit the ow of iluid. At a sufti- 5o cient distance below the partition 7 is secured a bridge 12, having a central opening 13, and serving as a guide for the valve-stem, the bridge itself having suitable openings to permit the passage of the fluid. Below the valve- 5 5 stem is a loose float 14, of cork or other suitable bouyant body, adapted to rise to the surface of the gasoline and to lift the valve-stem and valve.

In use the normal and closed position of the 6o devices is indicated 'in Fig. 2. When by generation of heat in the burner the upper portion of the stand-pipe becomes heated so as to generate gas, the pressure of the gas in the stand-pipe will force the iioat and also the gasoline downward somewhat, as indicated in Fig. 3, and so will permit the valve and its stem to gravitate, as indicated, and thereby free the port for the iow of gas from the stand-pipe to the burner, and this condio tion will continue so long as the flame continues at the burner; but when the flame is extinguished, the float will immediately rise and litt the valve toits seat and thus shut oft the escape of iiuid.

Having described our invention, what we claim is- The combination with a burner and a pipe for conducting gasoline upward thereto, ofI a transverse partition in the pipe providing a port, a valve below the same having a valvestem extending above and below the port, a bridge in the pipe for guiding such stem, and an independent float in the pipe below the stem for co-operating therewith to regulate Athe feed, substantially as set forth.
